I am planning our lessons plans for next school year and I am wondering what books any homeschooling families use for their kids. I have two fifth graders, one third grader, and a preschooler. I am more concerned with the fifth graders, because I am using my old plans for the younger ones. I bought the Kingfishers, Encyclopdia of History, but wondering if anyone knows another good one I could get. What about Science? Any web sites would be greatly appreciated too!!!! I will look at all answers, so please help out a fellow homeschooling mom!
